The beauty of auxillary cruisers is that they are standard merchant boats that can be converted to warships. That means there should be no obvious clue they exist and so cannot be planned for.
Remember it's very difficult to sink a warship but it's relatively easy to mission kill a warship.
BTW according to this website Bismarck Armour Protection
The Bismarck used 19,082 mt of armour material in it's construction. including ( but not limited to?)
How much of this material is directly comparable to tank armor I don't know but you are not going get anywhere near the amount of tanks that counting the tonnage of the ship might indicate.
- St 52 KM. Construction grade steel with a tensile strength of 52-64 kg/mm², a strain of 21% and a yield point of 36-38 kg/mm². This material was used for plates with a minimum thickness of 4 mm. Thinner surfaces used St 42 KM.
KC n/A (Krupp Cemented, new type). Face-hardened armour steel. This material contained 3.5-3.8% nickel, 2% chrome, 0.3% carbon, 0.3% manganese, and 0.2% molybdenum, and it was used for the side belt, turrets, barbettes, and conning towers. The 670 Brinell face-layer tapered in hardness as it extended into 40-50% of the plate's total thickness. Post WWII proving ground test indicated that KC was only slightly less resistant than British cemented armour (CA), and markedly superior to US Class A plates.
Wh n/A (Wotan hart, new type). Homogeneous armour steel with a tensile strength of 85-95 kg/mm², a strain of 20% and a yield point of 50-55 kg/mm². This material was used for the armoured decks, and, in the thickness employed aboard the Bismarck, was the equal of most foreign homogeneous plates.
Ww n/A (Wotan weich, new type). Homogeneous armour steel with a tensile strength of 65-75 kg/mm², a strain of 25% and a yield point of 38-40 kg/mm². This material was used for the longitudinal torpedo bulkheads.
I hold my view that the war was fought in the East as a Land campaign. So every spoon and ivory back scratcher spent on the Navy is hindering Barbarossa.
So the need for battleships is very small.
The British would have to counter the new French, Italian, American and Japanese battleships anyhoo so even if the Kreigsmarine built canoes, the RN would have to match the Littorios and the Richelieus.
The Light cruisers have the endurance/range of a bottle rocket. Leaves the Panzerschiffe heavy cruisers.The Panzerschiffe and the light cruisers are not Nazi era but Weimar era so the RN would still have to counter plus the Auxiliary Cruisers.
The 11 guns can go through the deck armor of most of the old battleships and the belt armor of the Repulse and Renown. The only capitol ships as fast as the Scharnhorst class aside from Hood.So you only talking Scharnhorst, Tirpitz, Bismarck and Gneisenau as battleships. The Scharnhorst 11 inch guns are not getting through the belt armour of any big gun battleship. So that leaves the 15 inch gun ships and that's not much.
Anson and Howe weren't completed until the middle of 1942 and the Lion and Temeraire were broken up on the slips.The 5 KGV was going to happen anyway and the only change was the 4 Rs were kept in service. The Rs were used as merchant escorts because a merchant ship was the only slower ship on the seas!
Yes they are but stealth won't stop the Murmansk convoys.Auxillary Cruisers are stealthy.
Had Germany waited until say Sept 1941 to invade Poland, would the KM be any better off? Presumably Graf Zeppelin, Tirpitz and Bismarck have entered service, but so have four if not all six RN armoured fleet carriers and four if not all five KGV battleships. The French military will have had time to improve, including completing both Richelieu class, and having the latest Dewoitine and Arsenel fighters in wider service. Germany would have more U-Boats, but the RN also now has more destroyers. And without France or Norway in German hands, those U-Boats have very limited access to the North Sea and Atlantic.Naval Strategy is built strategy. You need time and Germany went to war well before the Kreigsmarine was ready
Problem is that to reach parity with the RN alone, the Germans are going to need 20 big gun battleships!
No one did. Britain got close, 5xKGV, 5xQE, 5xR and 2xN. They'll need to front their 3xBC to make up the numbers, but I don't want to be on Renown when facing Bismarck.Not even the Imperial Japanese Navy had that many Battleships...
